OpenClaw versions prior to 2026.2.1 with the voice-call extension installed and enabled contain an authentication bypass vulnerability in inbound allowlist policy validation that accepts empty caller IDs and uses suffix-based matching instead of strict equality. Remote attackers can bypass inbound access controls by placing calls with missing caller IDs or numbers ending with allowlisted digits to reach the voice-call agent and execute tools.
